摘要:
A fuel tank arrangement for a motor vehicle. The arrangement includes a fuel tank containing fuel therein and having a gas space disposed above the fuel, and a venting device connected to the fuel tank. The venting device includes an activated charcoal filter and a venting conduit connecting the gas space to the activated charcoal filter for establishing gas communication therebetween. A stop valve is disposed in the venting conduit and is adapted to open gas communication between the gas space and the activated charcoal filter during refueling. Moreover, a fuel separator is disposed in the venting conduit for separating fuel from a gas flow through the venting conduit thereby yielding separated fuel.

A pocket cage formed from a deformable sheet has a pair of side rings connected by a plurality of webs, each web having a projection comprising a folding of web material formed by bending at a plurality of bending points. At least the material in the middle of each web has reduced resistance to bending relative to the material in areas of each web other than the bending points. This folding is produced by applying opposing pressing forces on the front faces of the side rings using a tool. By placement of the middle bending point on either the outer surface or the bore surface of the web, the projection can be suitably selected to be radially inwardly or outwardly directed respectively.

A method for operating a gas turbine comprising a compressor, a combustion chamber and a turbine is to allow a particularly safe and reliable operation of the gas turbine. Furthermore, a gas turbine and gas and steam turbine plant, which are especially suitable for carrying out the method, are disclosed. For this purpose, the compressor discharge pressure is used as a control variable.

A pressure regulator whose initial pressure can be set by manually setting the initial stress of a control spring has a double-seated valve with an inner and outer valve seat and a valve closing element. The valve closing element divides a supply pressure chamber from a control pressure chamber and the latter from a pressure-relief chamber. The inner valve seat is arranged on a control piston which is loaded by the control spring. In order to set a higher initial pressure, the initial stress of the control spring is increased, in order to reduce pressure, the initial stress of the spring is diminished. During this process, the outer or inner valve seat lifts off temporarily from the valve closing element until equilibrium is reestablished by a corresponding pressure chamber and the double-seated valve closes. In order to compensate the hysteresis occurring here, a lifting device is provided which, when the initial stress of the control spring is reduced, briefly lifts off the inner valve seat from the valve closing element and then becomes inactive again. The superproportional pressure drop associated with this in the control pressure chamber has the effect that the equilibrium of forces for closing the double-seated valve is always produced after the outer valve seat is opened by the pressure increase.

The invention relates to a device and method involving closing clips designed for closing a flexible packaging tube, comprising two clip limbs (3) and a clip base (2) arranged between the clip limbs (3), the clip limbs (3) being disposed parallel to each other and perpendicular to the clip base (2). Each clip limb (3) has planar inner surfaces (4) each of which is oriented towards the respective other clip limb (3), and the clip base (2) has an inner surface (41) connecting the inner surfaces (4) of the clip limbs (3). The clip limbs (3) have planar side surfaces (6). When the clip limbs (3) are viewed in cross-section, said side surfaces (6) are arranged perpendicular to the inner surfaces (4) of the clip limbs (3), and the cross-sectional height of the closing clip (1) is smaller than the cross-sectional width (14) of the closing clip (1).

The device includes an air release valve for a fuel tank of a motor vehicle, the air release valve comprising a housing defining at least one inlet opening therein, a central axis and a wall disposed proximate the inlet opening, the wall defining at least two outlet openings therein, the two outlet openings being sized differently; a sealing seat disposed about the two outlet openings; a float disposed in the housing moveable along the central axis, the float defining a center aligned with the central axis; and a flexible membrane attached proximate the center and extending freely therefrom to seal the two outlet openings.
摘要:
In order to take account of coupling in the controlled systems and, in addition, regulating variable limitations and to permit reliable control of a gas turbine set, a method and a control device for controlling a gas turbine set is provided, in particular in gas and steam power stations, in which a regulating variable composed of a plurality of partial regulating variables is supplied to at least two servo elements of the gas turbine set, and in which the partial regulating variables for the individual regulating variables are formed from control deviations by means of individual transfer functions.
摘要:
A closing clip for sausage casings and the like, formed from a metal strip which is to be bent round the gathered casing end and of which the bearing surface resting against the casing end contains a friction-increasing impression. The impressions are provided so as to cover essentially the entire area.
摘要:
A regulating device for regulating the course of a gas turbine plant has at least one sensor for sensing a measurement variable and for outputting a measurement signal which represents the measurement variable; at least one adjusting system for influencing air and/or fuel supply to a combustion chamber of the gas turbine plant on the basis of a correcting variable; and a regulator connected to the at least one sensor so as to receive the measurement variable and to the at least one adjusting system for outputting the correcting variable, the regulator being designed to determine the correcting variable on the basis of the measurement variable received and its deviation from a pilot variable. At least one sensor is designed to sense the variation in time of at least one burner or combustion chamber parameter as measurement variable.
